SELF-DELETING PLASMID - A method of producing a selectable marker gene-free plasmid by culturing a plasmid containing a selectable marker gene flanked by site specific recombinase target sites in a host cell environment incapable of effecting recombination between the site specific recombinase target sites and subsequently culturing the plasmid in another host cell environment which is capable of effecting recombination between the site specific recombinase target sites, so that the selectable marker gene is excised. Uses of plasmids produced by the method for the production of recombinant protein for therapeutic and vaccine purposes, production of therapeutic DNA and DNA vaccines and delivery of recombinant protein and DNA to a patient using live bacterial vectors.

STYLUS AND TREATMENT HEAD FOR USE WITH A MEDICAL DEVICE - A stylus and a treatment head for use with a medical device for imparting a force is provided. The stylus allows a practitioner to maintain focus on the treatment location while adjusting placement and force. This is because a light signal is emitted in the vicinity of the distal end of the stylus, proximate the treatment location on the patient. Alternatively, an audible or a tactile signal is employed for feedback. As a safety feature, the stylus is provided with means to allow it to collapse at forces above the accept able limit.

Method and Apparatus for Orientating a Solid Growth Culture Medium Plate - An apparatus for orientating a solid growth culture medium plate from an original orientation to a worked orientation, the plate having a lid and a bottom, the apparatus including an orientation mechanism that includes opposed jaws able to receive and hold a plate therebetween in a held position that defines a notional tube above and below the plate, the orientation mechanism being mounted on a jaw support member such that the jaw support member is rotatable such that at least the plate bottom rotates about a generally horizontal axis that intersects the notional tube to orientate at least the plate bottom from the original orientation to the worked orientation.

Method and Apparatus for Inoculating and Streaking a Medium in a Plate - An apparatus for inoculating and streaking a solid growth culture medium in a plate, the streaking using a streaking applicator having a line of resiliently and flexibly supported spaced apart contact surfaces, the apparatus including: (a) an inoculating and streaking station including: a plate work position having a notional action line fixed in two dimensions (x,y) in a predetermined position; and a plate rotation device for rotating a positioned plate to cause streaking; (b) a sensor capable of locating the surface of the medium in a positioned plate to thereby determine for that plate, prior to inoculation and streaking of that plate, the third dimension (z) of the action line; (c) an inoculating device capable of dispensing inoculum, along the action line, on the surface of the medium in the positioned plate; and (d) a streaking device capable of moving the streaking applicator such that its line of spaced apart contact surfaces contacts, along the action line, the surface of the medium in the positioned plate, prior to rotation of the positioned plate for streaking.
